Next came the vaunted 6600, after almost not being funded to completion. It waws the first true supercomputer. Cray had moved his team up to Chippewa ^^^^???
I used to play with a 6600. It had some interesting hardware features: * It used one's complement rather than two's complement to represent negative integers. (I.e. -x is the same as not x; a pattern of all 1's is '-0'.) * It had 60-bit words for both integers and single-precision reals. A 120-bit double precision was pretty slow. A word could fit 10 6-bit characters, but any kind of text processing was a bitch. * 15-bit addresses referred to the whole word. A word could contain several instructions, but only an instruction on a word boundary could be a target of a branch. --- Dr.Dimitri Vulis KOTM Brighton Beach Boardwalk BBS, Forest Hills, N.Y.: +1-718-261-2013, 14.4Kbps
